nonsnsnon Specification of Letters Patent. PatentedJan, 113, 1920 Application filed August 9, '1919. Seria1'No.*316,'3'41.

ing in New Haven, in the county of New Haven and State of Gonne'c'ticut, have invented a new and "Improved Horse'shoe,-of which -the following is a specification.

My invention relates more especially to that class of horseshoes having a cushion or pad comprising the bearing surface thereof, and an object of my invention, among othersfis to provide a s'hoeo'fthis class having means to soften the efiects of blows upon the cushion in the use of the shoe upon the hoof of an animal.

One form of horseshoe embodying my in- '1 Fi 3 is a detail view in section through the 5 0e on plane denoted by dotted line 33 of Fig. 1.

Fig. 4; is a detail view in section through the shoe on plane denoted by dotted line 44 of Fig. 1, but not showing the cushion in lace.

rior to my invention it has been customary to provide a shoe with a groove or recesses on the bottom to receive a packing or packings, in some cases such grooves extending more or less around the entire bottom surface of the shoe, and in other cases recesses being provided at intervals. These grooves and recesses have been filled with cushions composed of various materials that, owing to the severe wear to which they are subjected, must be quite compact and dense, and this feature of compactness and denseness increases as the shoe is worn in use, with a result that the cushioning effects desired are not as prominent as might be wished. It is to overcome this defect and render the fibrous material softer, thereby having a greater cushioning effect, that I have invented the shoe shown and described herein that consists in so supporting the cushion that it shall have more or less resiliency.

One form of shoe embodying my idea is illustrated as embodied in the form shown in "the drawings herein which' the num'eral '5 "indicates =the-shoe -having a groove 6 extending around it to receive the cushion- 7, said shoe being provided with any suitable means, as nail-holes '8, for securing-it in place. In the special form of shoe selected by me for the purpose of disclosing myinvention-herein,lateralextensions aaare located at the heel part of the sho'e, these extensions each having a double -groo ve comprising. channels 10in which the cushion 7 is located, said cushion extending across the opening between the ends of the lateral extensions and in practice the cushion occupies also the part of the groove 6 and the channels 10 shown vacant in Fig. 1. The shoe thus far described is of old and well known construction, and forms, except in connection with other elements to be now described, no part of my present invention.

In providing means to lend resiliency to the cushion I employ cushion rests 11 rising from the bottom of the channels in which the cushions are located. These rests may be of various forms, as shown herein they are short ribs or lugs extending from opposite sides of the channels partially thereacross, such rests being arranged in staggered relation. At those ends of the channels 10 nearest together the rests comprise ribs 12 extending across the channel, and toward the toe of the shoe and preferably extending lengthwise of the channel are ribs 13 that gradually merge into the bottom of the channel toward the toe. In all cases, however, these rests rise a short distance only and sufiicient to support the cushion with a space between its under surface and the bottom of the channel, and said cushion has, therefore, not a solid foundation, but its fibrous nature will cause it to give under the blows delivered to the cushion in the use of the shoe upon an animal, the ribs sinking into the substance of the cushion and the cushion sinkin into the spaces between the ribs under suc force, and the cushion is thereby caused to be yielding and resilient and to have a cushioning effect not present in devices in which such cushion is seated firmly against the bottom of the groove throughout its entire length.

I claim 1. horseshoe comprising a base having a channel in the bottom thereof, narrow rests rising from the bottom of said channel 7 to penetrate a cushion, said rests being spaced a substantial distance apart to permit the cushion to sink into the spaces between the rests, a cushion seated against said rests, and means outside of said channel for securing a shoe to a hoof.

2. A horseshoe comprising a base having a channel therein, rests extending from the bottom of the shoe and from one Wall and with their ends spaced from the opposite Walland arranged in staggered relation, a cushion located in said channeland seated against said rests, said cushion being unrestricted for elastic action in the direction of depth of said channel, and means outside of said channel for securing the shoe to a hoof.

3. A horseshoe comprising a base having a channel in the bottom surface thereof and extensions from the base, said extensions containing a portion of said channel, rests extending from opposite sides of said channel, a rest extending across the channel at the ends of said extensions, and a cushion located in said channel and seated against said rests.

4:. A horseshoe comprising a base having a channel therein, rests projecting a short distance from the bottom of said channel and spaced apart, and having their edges formed to facilitate penetration of a cushion, a cushion locatedin said channel and seated against said rests, the latter being of a Width and the cushion being of a flexible material to cause under pressure the rests to sink into the material of the cushion and the material of the cushion to sink into the space between the rests, said material being unrestricted in its elastic action, and means outside of said channel for securing the shoe to a hoot.
